NOTICE
Do not fill the cooling system faster than 5 L
(1.3 US gal) per minute to avoid air locks.
Cooling system air locks may result in engine
damage.
2.
Fill the cooling system with Extended Life Coolant
(ELC). Refer to the Operation and Maintenance
Manual, “Fluid Recommendations” topic
(Maintenance Section) for more information on
cooling system specifications.
Note:
Open the air vent (4) in order to allow air to be
removed from the system. Fill the cooling system
until coolant free of air flows from the vent . Tighten
the air vent securely. Ensure that the filler cap is
installed before operating the engine.
3.
Start the engine. Operate the engine in order to
purge the air from the cavities of the engine block.
Use the normal shutdown procedure in order to
stop the engine.

4.
Remove the filler cap. Check that the coolant level
is within 25 mm (1.0 inch) of the bottom of the filler
pipe. Clean the cooling system filler cap (1) and
inspect the seal (2). If the seal is damaged,
discard the old filler cap and install a new filler cap.
If the seal is not damaged, use a suitable
pressurizing pump in order to pressure test the
filler cap. The correct pressure is stamped on the
face of the filler cap. If the filler cap does not retain
the correct pressure, replace the filler cap.
5.
Install the cooling system filler cap.
6.
Start the engine and operate the engine. Inspect
the cooling system for leaks. Ensure that the
cooling system operates at the correct
temperature.

NOTICE
Care must be taken to ensure that fluids are con-
tained during performance of inspection, mainte-
nance, testing, adjusting and repair of the product.
Be prepared to collect the fluid with suitable contain-
ers before opening any compartment or disassem-
bling any component containing fluids.
Dispose of all fluids according to Local regulations
and mandates.
NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.
Clean the cooling system and flush the cooling
system before the recommended maintenance
interval if the following conditions exist:
• The engine overheats frequently.
• Foaming of the coolant is observed.
• The oil has entered the cooling system and the
coolant is contaminated.
• The fuel has entered the cooling system and the
coolant is contaminated.
Note:
Refer to Perkins Diesel Engines Fluids
Recommendations, Coolant Recommendations
(General Maintenance) for more information on the
service life of the recommended coolants.
Note:
When the cooling system is cleaned, only
clean water is needed when the coolant is drained
and replaced.
Note:
Inspect the water pumps and the water
temperature regulators after the cooling system has
been drained. This is a good opportunity to replace
the water pumps, the water temperature regulators
and the hoses, if necessary.
